Found in Colombia on the Cordillera Occidental at elevations around 2440 meters as a medium sized, cold growing, caespitose terrestrial with erect, branching when mature, cane-like stems carrying all along the upper half of the stem, basally deciduous, narrowly elliptic-oblong, rounded, margin finely erose towards the apex leaves that blooms in the later summer on a terminal, without a spathe, suberect, short, compact, on a mature stem or the branches, occuring only once, peduncle with a sometimes foliaceous bract at the base, racemose, rachis sinuous, .6 to 1.2” [1.5 to 3 cm] long, successively 1, 3 to 4 flowered inflorescence with prominent, longer than the flower, progressively shorter above, triangular-ovate, somewhat carinate towards the apex, obtuse, margin entire floral bracts and carrying non-resupinate, fleshy, ochre colored flowers with the base of the column green and the apex white.

"Epidendrum platystachyum belongs to the GROUP Macrostachyum, which is characterized by the erect, branching, canelike stems the base of the inflorescence without obvious spathaceous bracts, the erect or arching inflorescence with many flowers, the very fleshy lip that is folded and embracing the column, and the nectary pubescent to papillose in front of the stigmatic cavity. The new species is recognized by being much smaller overall, the inflorescence short and compact, the rachis sinuous, with successive flowers, the flowers ochre in color, the wide floral bracts, embracing the short ovary and flower, the oblanceolate petals and the small, narrowly ellíptic-oblong, rounded leaves. Epidendrum microcarpum Hágsater & Dodson is similar in size, the elongate raceme is laxly flowered, the bracts smaller, narrow and acute, the petals oblong and the leaves elliptic-Ianceolate and acute. Epidendrum chondrochilum syn Epidendrum macrostachyum is larger overall, with many flowers." Hagsater 2014
